Keith Ging, senior hydrologist in the Hydromet Operations group of the Lower Colorado River Authority (LCRA), has a Texas-sized challenge.

Mixing and dilution of effluents discharged into the ocean is an important aspect of health of ocean users and the ecology of the denizens.

India is emerging as a world leader in irrigation schemes, and the 458-km Narmada Main Canal – the largest concrete-lined irrigation canal in the world – stands as a monument to the opportunities and challenges that face water providers.

Exploring a coral reef is a big adventure for most people

An ambitious plan to turn back the hands of time by nearly a century on the Elwha River in northwest Washington State is being carefully studied by stakeholders on other river systems where long-standing dams may someday be breached.

Surveys were conducted at three mining pits in January 2018 using the Xylem UK rQPOD radio controlled vessel and the SonTek HydroSurveyor-M9 system over two days. Speed of sound in water cor- rections, an integral part of any acoustic survey, were carried out using the SonTek CastAway-CTD. HYPACK software managed the prepara- tion, survey, processing and outputs for the survey.

The group selected the Ruki River, a large centrally-located tributary to the Congo. The Ruki represents only 5% of the total Congo Basin by area but is uniquely blanketed by homogenous pristine lowland forest land-cover.
